TEST: GPC 

SAMPLE BACKGROUND: 

The sample submitted with the attached analytical request was analyzed using conventional GPC to determine the apparent molecular size in solution. 

EXPERIMENTAL INFORMATION: 

The sample was analyzed using size exclusion liquid chromatography with a three-column bank employed to separate species by molecular size in solution. The mobile phase was tetrahydrofuran. The columns and detectors were maintained at 40CC. 

The calibration of the system was accomplished using monodisperse polystyrene standards, thus the values reported are relative rather than absolute to polystyrene. The molecular weight range of the standards was 2 million to 162 Daltons. Please note that reported values are accurate and reproducible only to three significant figures; instrument software will not allow analysts to delimit the number of significant figures in the system. 

RESULTS AND DISCUSSION: 

Please note that a portion of the low end of the distribution had to be excluded as it fell outside the low end calibration range limit of -26.5 minutes. A copy of the analytical request and the chromatogram with the table of data has been attached to the report that is forwarded to the sponsor and the original is placed in the Analytical sample file. Should a copy of the chromatogram and molecular weight data be needed either as a hard copy or in a Word document, please contact E. Thompson.
